Question

What is the slope of (0, 2) and (-10, -16)

Answer 1

y=1.8x+2

Explanation:

y=ax+b

(0,2) means 2=b

(-10,-16) means -16=-10a+b

-16=-10a+2

-18=-10a

a=1.8

y=1.8x+2

Answer 2

m = 9/5

Explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

Points are (0, 2) and (-10, -16)

We see the y decrease by 18 and the x decrease by 10, so the slope is

m = -18/-10 = 9/5

So, the slope is 9/5
